Used in microbiology for the selective isolation and differentiation of Candida species, particularly Candida albicans, from clinical and non-clinical samples. The medium contains inhibitors that suppress the growth of bacteria and non-Candida yeasts, allowing selective growth of target organisms. Candida colonies exhibit characteristic colors, such as dark brown to black with a brown halo for C. albicans, due to the bismuth sulfite indicator and other components, enabling easy identification and differentiation. Commonly used in medical diagnostics, food testing, and environmental monitoring to assess fungal contamination.
